broken coil balance

Many thanks for writing in. You will need to remove the coil spring, plastic cover and pivot shoe from the window. Take photos and give us the width and thickness of the pivot shoe, as well as any stamped code on the coil spring; this should be near the end of the spring. We also like to see the pivot bar on the sash that goes in the pivot shoe. Let us know your findings. If you need help with removing the coil spring assembly, see the video below for details.
